In 1975, a 29-year-old white woman was diagnosed with Wilson's disease by neurologic examination and the presence of Kayser-Fleischer rings. She was given penicillamine (0.5 mg twice daily), which reversed most of her symptoms, and the Kayser-Fleischer rings disappeared. Approximately 14 years later, an acneiform eruption developed on her neck that persisted for 1 year.Physical examination revealed erythematous papules in an arciform pattern on the anterior neck (Figure 1).
